The work involves the construction of an overhead transmission line spanning almost 80 kilometers of the Ormoc-Babatngon 138-kilovolt (kV) line in Leyte, the grid operator said. It also covers the installation of upgraded equipment at the Ormoc and Babatngon substations.

The line will serve as the corridor that will transmit the power supply from geothermal plants in Leyte to Samar Island.

It will also increase the reliability of power transmission to Samar, which has no internally generated power, and is dependent on the supply from Leyte.
